Is just the drive through open or is the dining room open too?

I believe only drive up at night is open. Be cautious its not in the best area. There are usually lots of addicts around that area. If you drive over you should be fine, but I wouldn't advise walking from nearby hotels at night.

The drive through is open however Boston Medical is very close and there are many addicts near the gas station and near the store so that something to be a where of

Yes, there is dining! Obviously!

You can go in
