Fast food - Two Macdonalds, Burger King, two Subways, various pizza takeaway places (Dominos, Pizza hut, Pizza express, various kebab shops... I would highly recommend Roosters Peri Peri chicken. It's halal and serves very inexpensive but absolutely delicious chicken meals, including wraps, burgers, etc and even apple pies and ice cream in the summer. Try the chickenburger meal. Yum. For a sit down, go to Pepe's, opposite the indoor market (behind Poundland) which serves Greek Cypriot fare as well as burgers, steaks, sandwiches, puddings etc.
Halal - Roosters (burgers, chicken wings, chips...), various kebab shops.
Cafés - Presence coffee shop with paninis, muffins, with a spa upstairs and a gift shop out front. TJ Hughes has a restaurant/café, as does BHS. For the more traditional fry up, head to Aroma at the bottom of the high street for relatively healthy and delicious breakfasts, chips, burgers etc. Toast, next to Roosters and almost opposite the Palace Theatre, serves sandwiches, juice etc. Try Go Kula cafe on Market Place for vegetarian food but it is a bit hit and miss. Best to go there for a chat, read a few books and meet the local mums and toddlers. The YMCA serves good food - it is behind Poundland/next to the indoor market.
Coffee Starbucks and Costa in the Harlequin, Caffe Nero by St. Mary's Church on the High Street, Presence in the north end of the High Street, McDonalds on either end of the High Street... Plenty of places with plenty of choice.
Watford Town Centre comes alive at night particularly on Mondays, Fridays and Saturdays. The bars and clubs are practically all positioned next to each other up the High Street. As a general rule the music is louder, the drinks are more expensive and the atmosphere is more lively the further up the High Street you go, though there are exceptions.
A flyover divides the strip into the 'High Street' and 'The Parade'. Starting from the High Street and walking up:
Premier Inn, Hilton, Park Inn, Travelstop, The Grove (tres expensive but tres beautiful), Travelodge x2, Holiday Inn Express... Expect to pay around £70-80 to stay in the brand names. For B&B stays, try Berry Grove Lodge (01923 218015), The Orchard House Guest House , Ricky Road Guesthouse .
