I was intrigued by the fact that Los Arcos had a buffet for lunch...you don't see many mexican lunch buffets. I came by myself, the place was hopping with a lot of guys you could tell were work buddies but I was still seated immediately and had water and chips waiting when I got back from perusing the buffet. All of the staff were working their butts off, especially Carlos who was my server. The buffet had everything you would think a mexican buffet should have- build your own tacos, taco salads, fajitas, enchiladas, plus some extras: chilaquiles (!), watermelon, some good looking sauces/salsas. I was surprised that the buffet didn't have soggy overly oiled food...but they were replacing empty pans constantly so there were a lot of fresh options. It's a great deal for 7.50 and the locals seem to know it.
