Its opened from 7pm till almost 4am in the morning.

Not sure if this is a serious question. But no, there is no rabbit meat here. Thai people are not too fond for rabbit meat

How to get there:  Ride the MRT to Huai Kwang station. From Huai Kwang MRT Station, take exit 3.  You'll see steps going down.  From the steps, turn your body to the left and walk down the sidewalk along Ratchadaphisek Road to the corner of Pracha Songkhro Rd.  [about 50 steps].  Across the street is the Ganesha shrine.  Go down to the left of Pracha Songkhro Rd. to go to Huai Kwang market.
