london west end restaurant recommendation

[vale]

i'm going to london with my sister in 2 weeks time for a weekend for her 30th birthday. We are seeing Chicago at the Garrick at 8pm Saturday. Any recommendations for reasonably priced pre-theatre restaurants for dinner, preferably not a nationwide chain and it doesn't have to be child friendly as we are child free for that weekend only! Haven't been to London for a while and sis has never been!

Wahaca in Covent Garden is delicious - 'street' Mexican food from a Masterchef winner. Can't prebook tables though so bit of a gamble if you'll get seated in time.
