Perhaps it was overhyped in my case.... I went for the first time this past weekend.
I would give it 3.5/5 because to me it didn't taste much different than any other burrito place.
Yes it's cool that they have 40-50 different types of hot sauce. He and about 9 to 10 different types of salsa varying degrees of hotness. But those seem more like novelty factors than a reason to give this place A rating of 3 1/2 out of five or more.
The ambiance definitely was cool also cool is the fact that they have some light bottled beers, two beers on draft, as well as some Mexican sodas.
And if you just feel like water - you can pour your own glass near the self-serve salsa counter.
I got the classic Wilbur burrito with chicken and it seem like it had a lot of rice & a side of tortilla chips. I got all of their veggies that come w/ it but could not taste a trace of the charred corn.
The tortilla chips and homemade guacamole did not disappoint! Definitely get those ($5).
