Joining forces can be a sound strategy for success, unless it's with the Aqua Teen Hunger Force, who're generally pretty worthless with the exception of that one guy who turns into a meat igloo. Coming together for the sake of your tummy, the crew behind Toki Super Fusion, now open. After shuttering their Allston hot pot spot last month, the owners of Shabu Shabu have joined forces with Brookline's acclaimed Super Fusion and opened TSF, an 88-seat upscale Japanese resto featuring a dark hardwood floored dining room with a 6-seat sushi bar and red/green paint job evocative of everyone's favorite holiday: Respect-for-the-Aged Day in Japan, of course! New specialty maki include lemon sauce'd fried papaya/cream cheese topped with smoked salmon and wasabi; the Pink Lady (seasoned tuna, spicy scallop & cucumber); a fried butterfish roll w/ apples and crunchy tempura; and the unagi Allston Maki with lightly torched white tuna, spicy mayo, and a weird habit of ending nights at The Avenue. For (ca)noodling, there's a Tonkotsu ramen w/ berkshire pork slices, poached egg, and black mushroom; Shoyu (soy sauce broth w/ fish cake, seaweed, and scallion); and bamboo shoot, fried shallot, and cilantro blended into a salt flavored broth that's spent 10 hours simmering, but not sim-simma-ring, because then it'll probably forget who has the keys to its beemer. If you're interested in small plates because of poor body image/poorness, TSF serves a chopped salmon tartare w/ avocado and sesame miso, a seared rib eye pepper beef tataki in a spicy garlic sauce, and a lemon cream sauced, banana battered fatty salmon -- eat enough and your only strategy for success might be nicknaming your belly Master Shake.
