I have been going a little crazy with online vouchers lately and got a good deal to take the whole family here for burgers and milk shakes. You can make your own, chicken or beef, and they are fantastic. The kids thoroughly enjoyed their milkshake in a glass and neither could finish their burger and chips. The chip serving was reasonable and I just love the double bacon on my burger. Have already purchased another voucher to take the family again before the school holidays end.

Approximate cost: $34

This is a great little place located inside Adelaide's Central Market, has lots of outdoor seating, as well as plenty inside, good ceiling fans for very hot weather.
I had a chicken schnitzel burger, with chips, the portion was very large and the food very good, and very reasonably priced!
Staff were friendly, and when I stayed at the table long after I'd finished eating, reading the newspaper and enjoying being off my feet, there was no pressure on me to leave.
Would go back there next time I'm in Adelaide.

NOTE: I see there is a restaurant reviewed named Charlie's Shack, with a similar address - from the reviews, this appears to be a Vietnamese restaurant, and Charlie's Coffee Lounge definitely isn't a Vietnamese establishment. Please don't confuse the two - perhaps management has changed and the restaurant has changed, I don't know.

Approximate cost: $11.00
