This is the place my kids ask to go for in the Museum District. In fact, I think that most the time they want to go to the museums or on bike rides through Hermann Park, they are actually hoping I'll agree to lunch at Bodegas Taco Shop!
It's a casual shop where you order, tell the staff how to construct your taco and pay the cashier. You fill your drink and take your seat.
The restaurant is casual and good for families... but we usually opt for the patio because of our bikes and strollers and kids and circus we bring with us!
There are kids meals for about $5 and adult combos around $10 (and single tacos for less).
