Surrey has a number of neighborhood pubs where food can be found reasonably cheap - usually $5-8 for a burger and fries and around $10 for an entree. It is worth noting that BC has very high taxes on liquor, so although the food is reasonably priced at pubs, alcoholic beverages can be quite expensive with a jug of beer costing between $12 and $18 and highballs upwards of $5 each.
Those looking for a vibrant nightlife are advised to look to Vancouver, which has a number of popular bars and night clubs on its Granville strip.
