Siripanna is down the old Saraphi road, turn left (where you see the Siripanna sign :G ) and go past the Gymkhana Club, keep on and you'll find it, on your right. 599 grub buffet for adults, or 999 with wine. Greg and I took the womenfolk and kids, (5 adults 2 kids) 3 of us did wine, they made a special birthday cake for Greg's daughter, we had superb attentive service, grub was great, did about 5 or 6 bottles of wine, 4,800 all told.
Btw the 200 baht buffet is the Businessman's Buffet Lunch, Mon to Fri. (Some lovely totty get's in there for the lunch buffet too! )
Yep, I posted pics of it at the head of this thread.
The food at HI may be a cut above, but the service and ambiance at Siripanna (I'm a Brit biker all right? These things are important to the likes of Ogri 'n' me!) beats HI hands down.
