My company pays all travel expenses, e.g. airline tix, hotel stays, taxis, rentals cars, client dinners, etc. If you are staying a a relative's house during the business trip, you can claim half of the regular hotel cost as your own. Need to keep all the receipts though.

They also provide us with a daily travel stipend that is based on position, e.g. 50 for all non-managerial positions, $75 for section chief, $125 for managers.

Although they don't specifically pay for meals, usually one can keep most of the stipend by eating the breakfast included in the hotel stay, and lunch or dinner functions with the clients. Very rarely do one get to spend all of his/her stipend on food, unless you want to order a full five course room service every night.
