Where are you actually heading to? The inexpensive places in GC have all gone. There's a place on the main road (by passing GC) just beyond Bounty and the pharmacy on the right side (no water view) very inexpensive but I can't remember the name.

Lots of inexpensive places but not GC. Concordia has a few, Jordan Village Maho area, Fat Tonys, Yvettes, Quartier d'Orleans.

But if it must be GC and water view I'd say NICE. It's where a seafood place used to be near a clothing store, across from parking lot.
