The prices have been slowly creeping upwards every year - now its $18, $28 and $38.
Originally it was $15 and $25, then they added the $35 category, now each has been bumped up $3.
Anyways, one that isn't trendy etc. but has consistently good food is Rex Rotisserie & Grill @ Bentall Centre. Good sized portions, good selections (more than one dessert offered) and isn't so crazy busy that the servers ignore you - and it's $28.
Had a bad experience at Flying Tiger a while back (non-dine out) - they lost our order and we waited over 1.5 hours for our food - even after pestering the servers (who must not have followed up on the orders). Never going back there again.
