We were in Tlaxcala this past weekend and tried the breakfast buffet at the Cafe Los Portales since it ranked high on the list on tripadvisor. However, I have to disagree with the reviews in the past. We found the only plus of this restaurant was the location. It is extremely convenient since it is located right in the middle of the Zocalo. The food was so-so and the service was poor. The tortilla grill girl was impatient when there are more than three customers there placing order at a time. I have seen many juggled between 5 to 7 customers with complex orders and got the orders correct. This one may be inexperienced, but the attitude was not favorable. The waitress scolded at us for not being able to finish the way too spicy soup. We didn't leave the whole bowl un touched, only the very little which it had gotten too spicy and it started to hurt our throat... At the end, the server took out her own propino without consulting us. Please avoid this place if you can.
