Love Mac's Shack. Went with my date for a 6 PM Happy Hour. We sat at the bar and Ethan served us well for an hour. I had a lovely Petron Margarita on the rocks, no salt. My date loved his Absolute Bloody Mary with a huge shrimp. We had 6 littlenecks and 6 wild Wellfleet oysters. WOWSA..so fresh. We then ordered a Spicy Tuna Mango Martini with amazing chips and the Wave Roll which is spicy tuna, shrimp tempura, avocado, cucumber, wrapped in soy paper. It was sublime. Bars don't get cooler than this...the setting, the vibe, the bartender, the food..LOVE LOVE LOVE it..
