So I guess this is turning into a burger joint discussion...I'll jump in 
One of the burgers I've had was Hard Rock's. Rp 95,000 plus tax...it wasn't cheap, but they had a credit card promo (It think it was buy one get one), so it was ok.
One that was good and inexpensive, was T-Grill at Epicentrum, but too bad the place is closed and looks like it's not a chain either since I haven't found any other T-grill in town.
