Excellent skewer-spot on Hengshan Lu STYX has this unlimited skewers deal on Wednesdays from 6 to 9pm. For 188rmb, you get as many as you can eat, from a select group of 10 skewers (including 3 vegetarian options). Yeah, it says "unlimited," but STYX is not actually a portal to the skewer dimension. There is, in fact, a hypothetical limit to the skewer stock. Also note, whatever skewers you don't finish will be charged, to discourage wastefulness.
Cannery. Champagne. Campaign. Champaign. Every Saturday and Sunday it's buy-one-get-one on the entirety of the champagne list at The Cannery. Nice opportunity fancy drunk.
Chin Chin by Wheat has extended its free-flow on Gin'n'Tonys that runs from 5-9pm everyday for 150rmb. Yup, everyday. They come in those big balloon glasses, too, usually, which really helps you feel like you're getting your money's worth. Dovetails nicely with their 7-8pm tapas deal, too. Mind you, we've seen the wait times on those GnTs stretch to 20 minutes on a packed Friday night, so don't bank on slamming back four of them at 8pm.
Plus One More...
Last minute addition; Shake's doing half-price on all their cocktails every Thursday for the month of April, which is snazzy. Brings it down to like 45rmb on solid cocktails of the 'made-by-a-man-in-a-bowtie' variety, the kinds we've all sort of resigned ourselves to paying a cool hundred for. Plus, they've got that full band playing.
