Okay. Ian. I will try to cover as much of your question as possible, and obviously, Mariano will help me with that. So let's start with the first part, the same-store sales and let me say that we are very pleased with the improving trends of comparable sales in the recent months, and particularly in the recent weeks, as we mentioned in our opening remarks, October comparable sales rose to more than 90% of the prior year period.
So that's a sequential improvement when compared with the last month of the third quarter. And in terms of the different regions, I would say that, the Caribbean division continued to lead the way. Particularly in October, we generated in the Caribbean division, double-digit positive comps. So very strong results and a very important contributor to our results, given the fact that, as you know, there, we have many markets that produce results in hard currencies, which are very important for the company.
The other divisions also continued generating sequential improvements last month, and we are very excited with November figures. November continues to see improving trends. And we are pleased with the performance of each division. Each of them in a different context in terms of the operating conditions and government restrictions. But I would say that a good news coming from the sales part of the business.
In terms on-premise dining, I would say that the main challenges remain in the malls. Even though many malls have reopened, we are still facing some restrictions in terms of hours of operations in malls.
So obviously, there is a recovery in on-premise sales in all the restaurants that are allowed to operate their dining rooms. But particularly in shopping malls, we are facing some challenges, additional challenges, given the fact that, as I mentioned, there are still some restrictions, particularly there are still closed food courts in different shopping malls, and there are restrictions in terms of hours of operations.
I will talk a little bit about 2021. And as I mentioned during the call, we do not have all the answers yet, but we are advancing in our 2021 planning process. And as we mentioned, we expect to provide you with some visibility on what we plan ahead for our -- before our next earnings call. This is obviously -- or has been obviously a unique period in history. So we are focused on our plans for 2021, which is also how we are managing the planning process with McDonald's. In other words, for now, we are managing our openings and reinvestments plan on a year-by-year basis.
And as we look ahead, we have a robust pipeline of openings that will support our future growth in line with market conditions. So I expect in the coming weeks and months to go back to you and the rest of you and give some color in terms of what to expect in 2021.
And conversations with McDonald's are constant. And I think that we are pretty aligned in terms of the opportunities that we still have for the brand in the different markets, and we are very enthusiastic, building on the strengths and the market share wins that we already had this year.
In terms of margins and challenges for 2021, obviously, there are a lot of challenges. But I think that we are very pleased with the way we are managing the business right now and the way that we are keeping our margins growing month after month, quarter after quarter. Just as an example, maybe, the main area of costs in our P&L, food and paper, if you take a look to our food and paper as a percentage of revenue in the third quarter, it improved by 30 basis points and is basically flat for the whole year, for the first 9 months of the year, despite full inflation above CPI in many of our markets, particularly in Brazil.
as you know, there are some pressure coming from protein costs, protein cost pressures are a reality that the entire food industry is facing. So not just us, not just QSR or restaurants in general, but also groceries. But in that kind of scenario, given our scale, and our ability and skills of negotiation, I'm convinced that we are in a much better position than anyone else in the markets to deal with these kind of pressures.
And we have in place a full strategy team at the corporate level, and we have many management teams at the market levels, but our focus more than ever in managing the menu, what we sell, how we sell our menu or products, and improving our gross margin. And they are working in all the levers related with gross margin. It's not only cost, it's about prices, it's about promotions, it's about leveraging our digital capabilities to offer a segmented offer and different offers for these different customers.
So we will work hard to manage this effectively in 2021 through a combination of pricing mix, inventory management, supplier negotiations, et cetera.
So I think we are in a very good position to continue building on the strength we have this year. And improving margins in the coming months. I think that I cover most of it. I don't know if there's something missed, but thanks for the question, Ian.
