Cosa Sabrosa’s colorful food truck has become a familiar sight outside the Zal Gaz Grotto on W. Stadium Blvd., serving tacos and other Mexican fare. Until the weather turned cold last year, diners would pick up their orders and eat at colorful umbrella tables on the Grotto’s lawn or park themselves on the grass out front.

Now, Cosa Sabrosa has taken up digs inside the Grotto. In January, it began serving its Mexican-inspired menu five days a week, at lunch and dinner, from a location in the Masonic lodge’s front entrance. Cosa Sabrosa’s neon sign burns brightly in the Grotto’s window, while the truck is parked outside the door.

Indoor seating was not allowed in January, but customers can place carryout orders online, by phone, or in person. The restaurant encourages people to order in advance, because many dishes sell out.

The truck hit the road in 2016. Chef and owner Jeff Gardner currently offers eight different fillings for tacos, burritos, and nachos, including beef, pork, fish, chorizo sausage, sweet potato, and cauliflower (vegans can order the vegetarian options without crema). Three types of salsa are available.

Side dishes include rice, Mexican corn, two types of beans, guacamole, chips and salsa, and pickled vegetables. Drinks are limeade, horchata, and Mexican Coke.

Prices start at $3.50 for a single taco. A three-taco combo, with rice and beans, costs $12, while burritos and nachos also cost $12.

On its Facebook page, Cosa Sabrosa was offering a Thursday night special through Feb. 4: four crispy birria (stewed beef) tacos for $13.
