The Baja vibes are strong and the price is right every Tuesday at Summer Shack. Head to either the Back Bay or Cambridge locales for a Shack margarita and a fish taco for just $10. Grab a taco-tastic lunch or happy hour in Cambridge (open 11:30am) or have a dinner feast at either location (Boston opens at 4:00pm) of fish tacos along with some of the shacks tasty apps and mains like a Tower of Power (8 freshly-shucked oysters, 8 littleneck clams, 4 shrimp and 2 oyster-tuna sashimi) or a plate of their famous deep-fried whole belly clams. Make a reservation online here or just pop in to the location of your choice. Follow Summer Shack on social media (Facebook and Instagram) for more specials, and check their seasonal pop-up in Harvard square to get in a clambake party mood all summer and fall.
