Blue Guides seems to cater to the educated and curious tourist interested in the arts and history. Its _Rome Guide_ is pretty good to have in hand when touring (Krautheimer is just too big to lug). Yet its lodging and dining sections seem to have been added _pro forma_ -- as something such a guide ought have, yet not the emphasis.
_The Concise Blue Guide Rome_, just off the press, has -- despite its name -- more detail as to where to eat. Many of its recommendations appear on Chowhound.
Most of the eateries recommended which I know I can confirm. I would welcome Chowhounders' views on the following, which I don't know yet caught my attention:
LA TAVERNA DEGLI AMICI aka A Tormargana, Piazza Margana 37. Seems to be recommended more for location. "typical Roman fare and an impressive wine list"
ROSCIOLI, Via dei Guibbonari 21, is listed as a wine and cheese shop and otherwise "a place where you can sit on a stool at the counter to enjoy an excellent meal". I thought it was a restaurant with sit down tables. Can someone confirm?
IL MATRICIANO, Via dei Gracchi. Recommended for lunch. I've generally found the Vatican area an gastronomic wasteland.
DITIRAMBO, Piazza della Cancelleria 74: "a simple cosy place with two small main rooms".
"serves rather unusual dishes"
DA FORTUNATO AL PANTHEON, Via del Pantheon 55: "traditional Roman restaurant with particularly high quality food"
LA SAGRESTIA, Via del Seminario 89
MONTECARLO, Vicolo Savelli 12 "good simple local dishes". I myself am suspicious of places with pretentious names.
AL CEPPO, Via Panama 2 "grilled meats especially good".
LA SELLA DEL DIAVOLO, Via Ostiense 102 good for fish and Sardinian specialites"
SORA LELLA, Via di Ponte dei Quattro Capi. Chowhounders themselves have given decidedly different views of this place.
A closing word of thanks to Chowhound's Italian Board contributors, whom I've relied upon for several years.
