There is an innumerable choice and we recommend that you check your travel guidebook. We restrict ourselves to giving some options close to the university which we like personally.
Colazione + Caffè: “Pasticceria Primavera” in Via Sant’Ottavio (Sicilian dolci, also very good lunch), “Bar Verdi” in Via Verdi (also lunches), “Pasticceria Abrate” in Via Po (elegant, also aperitivi), “Bristol Concept Bar” (Via Sant’Ottavio), “Se puede” (Via Verdi), “Caffeine” (Via Po), “okcaffe” (in the McDonalds at Palazzo Nuovo) are some convenient options.
The standard price for a coffee is 1 € or 1,10 € “al banco” (i.e., standing). Simple coffee places bring it for the same price at your table. In more elegant places, usually recognizable by the dress of the waiters and/or the great location (e.g., Piazza Vittorio Veneto, Piazza San Carlo, …), they may charge you up to 2 € at the table. It is fine to ask about the prices before ordering!
Pranzo: Some suggestions are “Tre da Tre” in Via Verdi, “Caffetteria San Giorgio” in Corso San Maurizio, “Pasticceria Primavera” in Via Sant’Ottavio, “That’s a Mole” and “Bonta da Re” in Via Montebello, “Caffeteria Antonelli” at the angle Via Po/Piazza Vittorio Veneto, and “Brace Pura” in Via Roero di Cortanze. The places in Via Po tend to be a bit more upscale, but may offer more elegance. Typical Piedmonese cuisine at mid-range prices is served by “Bistrot Turin”.
Al Volo: The queue at “Accademia del Panino” in Via Sant’Ottavio is well worth it: you get excellent sandwiches for 3,50-5 €. Also “Monegato” in Via Verdi is decent for salads and pasta. “Moi Moi” in Via Roero di Cortanze offers Apulian fast food and pasta. Also McDonalds and Burger King have (after student protests…) conquered the surroundings of the university.
Caffè and drinks in an elegant setting: “Circolo dei Lettori” in Via Bogino (bar in a cultural association on the first floor of a historical building), “Farmacia del Cambio” in Piazza Carignano, “Caffè Elena” and “Caffè Fiorio (see below).
Gelato: “Alberto Marchetti” in Via Po, “L’Essenza del Gelato” in Via Principe Amadeo, “Gelateria Romana” close to Piazza San Carlo, various places in Piazza Vittorio Veneto and in Via Monferrato (close to the Gran Madre, on the other side of the river).
Aperitivi e Dopocena: “Caffè Fiorio” in Via Po (only inside) and “Caffè Elena” (inside/outside) in Piazza Vittorio Veneto. Both very traditional Turinese places with very good wines. Fiorio does apericena, Elena not, but you get, as in most places, some bites with the drink. Next to Elena is “Caffetteria Antonelli”, popular with youngsters and a nice view on the piazza. The same holds for the “Gran Bar” at the opposite site of the river. Classy place, hugely popular with the jeunesse dorée of the city. A very affordable option is “Caffè des Arts” in Via Principe Amadeo. Slightly trashy ambiente, but an excellent wine selection and decent food. (If you are on a shoestring, just leave the center and a couple of euros will get you very far, especially if you stick to vino sfuso.) For the digestivo, there are lots of nice places. “Gelateria delle Alpi” in Via Po is central and open until late at night.
Cena e Vino (very subjective selection): You get good Piemontese cuisine in “L’Angolo di Parìn” (San Salvario neighborhood, excellent price-quality relationship), “Taberna Libreria” (city center–à la carte a bit expensive, but a wonderful fixed menu) and “Le Vitel Etonné” (center, only à la carte and a bit upmarket). In general, there are many excellent places for eating in Turin; just ask your Lonely Planet.
Almost everywhere you get very good wine bottles in the 15-20 € range. Grapes/wines to try from the Piedmont are the Ruché (fruity), Barbera d’Alba, Barbera d’Asti (full-bodied), Dolcetto (a bit in-between; used to be the classical table wine) and Nebbiolo (tannic and light-colored). The deluxe version of Nebbiolo grapes are the famous Barolo, Barbaresco and Roero wines.
These are all red wines; the Piemontese white wines are less exciting. Try the Arneis, though, at aperitivo. The local “bollicine” (sparkling wines) are also very decent.
