They had bottles of wine (including champagne) and liquor out, as well as a couple of fridges full of canned beer, chu-hai and soft drinks. The bar was also manned and appeared to be serving drinks, though it was crowded so I stuck to the self-service options. For food they had a small salad bar, stir-fried meat, rice, etc. My memory of specific offerings is a little hazy at this point, but overall it was on par with what you'd find in a good airline lounge.
