Arusha has many interesting bars and restaurants. As a rule the best food is Indian, thanks to the large sub-continental community in the city. Liquid Blue in Njiro and Big Bite on the Swahili Rd are among the most popular Indian restaurants. For 'Nyama Choma', or Tanzanian roast meat, Nick Bar in Njiro is also popular. There are uncountable local bars which are generally welcoming to adventurous foreigners. The less adventurous visitors stick to Via Via, in the grounds of the old German fort, which is an interesting cultural centre and part of an NGO which trains locals in the hospitality industry.
There are plenty of options for bars and restaurants for those who for some reason seem to wish to avoid locals altogether; these places are very easy to find.
For nightclubs, the Velocity, Colobus Club, Maasai Camp, Triple A, 777 and Polygon Triangle are popular with locals and foreigners alike. They start late and finish very, very late or early. Pickpockets have been known to operate and all these bars are popular with the local sex workers so the usual discretion should be applied.
