At Mucho's you will find a wall behind the counter where 280 bottles of different hot sauces are on display. This is no joke. In their global jet-setting endeavors, the owners have picked up hot sauces from places as far away as Seychelles. I think.
They offer a very healthy selection of cheap Mexican food as well. Only a few of the hot sauces are available for your sampling at any given time, but there are a few mainstays worth recommendation, especially the firey hot Chipotle pepper sauce, which looks like dark brown slop as you pour it on your burrito, but has a scorching taste to die for.
Regular chicken burrito is $4. "El Gigante" is $5. Full dinner plates are also available. During the weekdays, this place is jammed for lunch as suits from the surrounding towers pour in for a quick meal.
And there is always salsa music blasting from the stereo.
