Overall a perfect experience for what I was needing today! Delicious Sautéed Veggie Bowl with the classic, delicious add ons that we've all come to love and appreciate! I thought I'd be taking some home...nope! ❤️😋

Food was ok, would not be not my first option for Mexican, ordered for convenience.
Ordered online for pickup, customers who ordered in store after I arrived got their food first (order 1 burrito and 2 quesadillas) were in
