<p>Hotel wise, look into the suggestions above. You should be able to find a decent rate at the Courtyard if you're there for a whole week. If you're looking for something really cheap, there are also a couple of cheaper hotels on Chapel, called the Duncan and Colony I believe. The Duncan is an older place, kind of like going back in time, so it's possible that a few of the rooms do not have air conditioning or televisions.</p>
<p>Food wise, there are a half dozen middle eastern restaurants scattered throughout downtown New Haven where you can have a full meal for less than $3. Or a dinner for $5 or $6, if you throw in some side dishes. There is a huge immigrant population in New Haven, which is why there are hundreds of ethnic restaurants there. There are even two really great Ethiopian restaurants right next to Yale. </p>
<p>Other great values include a couple of famous pizza places, which are nearly 100 years old and among the oldest and best pizza restaurants in the country, where you can get an amazing pizza, yes an entire pizza, for $5. As food is one of the great passions in my life, I've traveled extensively to Naples, all over southern Italy and to all of the top Zagat pizzerias in New York City, Boston and elsewhere, and honestly none of them compare to the $5 pecorino romano red pizza (order this, not the mozzarella) at one of New Haven's famous pizzerias, although I did find this place in the middle of nowhere in the countryside, far outside of Rome, that had a nice bufala pizza.</p>
<p>If you want to go to the fancy restaurants, of which there are many (certainly more than any other medium-sized city or college town in the country), your best bet is to go during lunch hours because lunch prices are significantly cheaper than dinner prices. One place to check out is called Ibiza, which Wine Spectator, Esquire, New York Times and other magazines have rated the best Spanish restaurant in the United States. The chef is from Barcelona. But try to go during lunch or you'll spend a lot of dough. You can get away with a $30 lunch. There is also a great Malaysian restaurant, packed every night of the week and a bit pricey for dinner, but where you can probably get a lunch for under $10.</p>
<p>There are also a few "burrito carts" from what I've heard, which are run out of one of the best, four-star restaurants in town (Roomba), and serve $5 burritos. If you go to Roomba itself you have to drop at least 50 bucks on dinner. If you're looking for good Mexican or South American food beyond these, there are some incredible places in the Fair Haven neighborhood, a mile or so east of campus and one of the centers of the Latino & South American community on the entire East Coast, complete with dance halls and everything, but you have to really know your way around or be with someone local in order to find and get to them. Easily the best Mexican food I've found in the States, aside from a couple of shacks I went to on the Arizona/Mexico border once.</p>
