pick your restaurant carefully, nothing too fancy... I would choose a upper end chain and take a book or computer with you everyone does it. I do my best writing in noisy places sometimes.
Yes. I don't do it often because I can't afford to dine out much so I would rather spend the money when it is part of socializing with friends. But I have done it plenty of times when traveling.
Yes I do. If you don't have a significant other and no friends are available to go with but you still feel like treating yourself what else are you supposed to do ?
