I've been to Fresco twice now. There are many things that I love about it, including: the atmosphere, the design and decor, the friendly staff, the daily specials, the drink selection, the reasonable prices for the amount of food you get, the website, the location, the cleanliness, the speed, and finally, the hot sauce and salsa bar.
However, the main point of a restaurant is the food. Unfortunately here it is a bit too bland for me. Even after adding a variety of salsas and cilantro to my burrito and tacos it just didn't have a satisfying taste.
Now, I must admit, I'm a bit of a snob when it comes to Mexican food. But with Fresco, I'm not even rating it on my authentic restaurant criteria, I'm judging it as an Americanized chain style casual fast food spot.
Bottom line: If they do a bit of tweaking to their seasoning and boost the flavor up a bit, I'll definitely be a regular customer.
