Dined in on a friday night around dinner time, during their opening week of business. Very impressive fast food restaurant in both concept and practice, with a varying menu and good execution.
Wife had the signature coney, which was finished with a great beanless chili. The chili is very mild, allowing the natural casing dog to have it's day. I had the fresh cheeseburger, which is actually a small double. The melted cheese and burger patties made for a wonderfully soft sandwich that edges towards a steamed burger.
Homemade coleslaw was served cold and crisp- a really good slaw. Home made onion rings were lightly battered and crispy. Hand cut french fries could be awesome, but ours were tepid and soft, having suffered from being in a styrafoam take out box even though we dined in.
Great service from the owners and staff far outweighed the multiple 1st-week hiccups. We found no garbage cans inside the garbage receptacles in the foyer; I'm sure they'll fix this oversight in no time. Serving ALL the hot dishes in styrafoam leads to many items being too steamy or damp even when immediately eaten. Again, I suspect the owners will make adjustments to the food packaging. The glaring issues are all things that anyone capable of such a great concept will quickly see for themselves.
The Coney Company is a excellent addition to the downtown Old Brooklyn neighborhood.
edit: not a 24 hr restaurant
