I will be three days in Montevideo with friends. We need to know good places to eat. It will be five people. All kinds of food are fine. Not too expensive.
I suggest you take a very idiosyncratic pizza at Bar Tasende. The place is big, so no problem getting your 5 friends sited. The pizza is drooling, although the service is a bit hard to get they attention. But once you do, everything is great and fast enough.
