With so many culinary traditions to draw upon, eating out in Vancouver is a varied and relatively inexpensive affair. The city is obsessed with its restaurants, and locals make a regular habit of trying new venues to wine and dine. As the tour guide pointed out, there is not a single person walking on the streets of Vancouver without a big mug of coffee or something to munch on. Q59. Which of the following is not a reason for the people of Vancouver to eat out? the city has many restaurants the food is not very costly people love eating people like to spend money on food Q60. Why does Vancouver offer a variety of food? its restaurants prepare dishes from different cultures the country has its distinct style of cooking the restaurants keep mixing new dishes the people need different foods at different times
