I would reccommend a place called Gyuma close to the Sukhumvit end of Soi Thing Lo.

Think it's abut Bt.299 each from memory.

Excellent Beef : )

The other day, we found the new location of Go Ki Jip is located on Suk Soi 34, about 100 meters off the main road, just a short walk from the Thong Lor BTS station.

Went to try this place the other day... They now have a "for sale or lease" sign on the door and were closed and out-of-business from all appearances.
