I've been to Calabash four times now and each time I am more and more impressed by the food, drinks and value. When it comes down to it, you're getting a great Caribbean meal and drinks for at least 20% less that what you'd pay at Earls or equivalent.
Also, the wait staff is incredible, super friendly and the owners are always around lending a helping hand.
Calabash has two floors and the basement hosts a DJ booth in which there are weekly schedules where it turns form a restaurant to a dance floor with the convenience a bar located downstairs as well.
I've only been on Saturdays and they have three DJs mixing awesome reggae beats.
Not pretentious at all, great food, great drinks, great people, great ambiance... don't think you could beat this in Vancouver.
By the way, I was there last weekend with a group of about 15 for my girlfriend's birthday and it was great. From dinner to dancing until 2am, it was just a blast.
