For cheap Chinese food, nowhere beats Jackpot. This casual restaurant serves a variety of dishes, with mains ranging from $6.80 to $10. They also offer the traditional starters such as Spring Rolls and Steamed Dim Sims, all for wallet-friendly prices. The noodle dishes are tasty but you can do better, although if we're talking value for money, they're certainly not bad.
If you decide to frequent this place, I recommend choosing one of the Chef's Specials which are all $10. I'm fairly confident you won't taste any difference between these and those from a more expensive restaurant. Salt and Pepper Squid is always a winner, and Jackpot's version does not disappoint so give that one a try if you haven't before.
The menu also boasts some oddly named items, like the Taiwanese Drunken Chicken, which I have not yet been brave enough to sample. Keep in mind that the dishes do not automatically come with rice and you have to order it separately.
There are three locations in Brisbane; West End, Toowong and Albert St. The menus do vary slightly and my experience is specific to the West End location. The Toowong store is currently being renovated but will reopen sometime in August.
