I was there end of June Sat lunch, Im guessing it was the upstairs that was open? I was actually really impressed. Its broken into lots of smaller spaces so it didn't feel packed even though there were a few people there. I thought the food was much, much better than the MEL lounge (lots of nice salad options). Im not sure if this is still the case. It's a lot more 'broken up' than the MEL lounge.
The MEL lounge has always been my favourite but I suspect SYD will become my favourite, especially as they have the premium entry and they are after security.
What's it like during peak times, i.e. 6am on weekdays? Standing room only?
