Didn't see a post on the relatively new grilled cheese shop in Park Slope on 9th Street in the old Almondine space. An import from Philly, Meltkraft was quite busy from the beginning. After passing by on a few weekends in the first few weeks, they were already sold out of many of their grilled cheese sandwiches by 1:00P. One Sunday I dropped by at 11A (when they start serving sandwiches) and ordered the Valley Thunder (cheddar, brisket and mac n cheese) and Melter Skelter (raclette, pickled green tomatoes, jalapeno, watercress). Both were very good and super rich. I think I may have preferred the Melter Skelter as the tart veggies and pepper watercress cut through the fattiness. I also ordered the tomato soup which was on the tart side -- also helpful in cutting the richness of the sandwiches.
In addition to the sandwiches, they also serve pastries from Balthazar Bakery, coffee, tea. It also functions as a bit of a grocery store where they also carry drinks, pastured eggs, charcuterie, cheese, cookies, etc. But the one item I was blown away by was their brownies. They look pretty unassuming with no label and wrapped in cellophane -- kind of like what you'd see at a bake sale. I don't think they're baked in-house as the guy at the front desk told me where they were from (just don't remember where). But they were one of the best brownies I have had -- dark chocolate, not too sweet, moist and with the right amount of chew (I prefer chewy brownies over cakey or fudgey ones).
