It was restaurant week so it was a good reason to splurge. The menu I chose was dim sum platter (good!), crispy chicken (too sweet), and macarons for dessert. Washed it all down with Agave No 8.
If you eat dinner, you can go to the club for free.
Pro tip: use Hakkasan's valet. Avoid the madness of MGM's valet, plus you won't have to walk across half the property
