Put a little pep in your workweek step with a stop at either of the two locations of LOCO Taqueria & Oyster Bar to have your fill of $1 oysters every Monday. Head to the original location in Southie between 11:00am and 12:30am, or pop over to their newer location in Fenway between 11:00am and 10:00pm to slurp your weight in shellfish and wash it all down with some of the city’s best margaritas and mezcals. Bivalves and a couple of tacos make an ideal lunch, or swing by after work for a bar feast of oysters, chips, guac and queso. Loco always has plenty of room for walk-ins, but if you want to save your seat, make a reservation for Fenway here and Southie here.
