Toast is more properly a lounge than a restaurant, occupying the former Elephant Walk/Rauxa/Macondo space. Petal Joseph, the former owner/proprietor of Supreme Sandwich in the Arsenal is the chef here (she was at Rialto previously). They have a small menu of tapas-sized dishes, all under $10. We had the spicy cucumber salad, which had a nice crumbled feta and a bed of small leafy greens. It wasn't at all spicy, but tasty nonetheless. The braised oxtail with root veggies and dumplings was delicious, perfect for a cold fall evening. Fried medallions of monkfish was slightly dry but tasty. These three dishes plus two drinks (one of which was a huge pour of wine) came to about $25, and fed two people (light-dinner style). The space is weird and almost empty, I don't know whether this is because it turns into a raging dance floor other nights (they have live DJs Thurs. - Sat.) or because they haven't finished the buildout. It appears to have been open for only a few days, and I'm willing to chalk up the disorganized service to that. I'm skeptical that this place can survive in that location, since the DJ crowd is mostly students and Union Square is not served well by the T.
