The rules actually differ a little for different orthodox denominations — for example, Russian Orthodox rules traditionally allowed for the consumption of beer throughout Lent (I'm not sure if that's still the case but it was for a long time), whereas in the Greek tradition, all alcohol is banned on the strictest days. A more significant difference regards the use of oils — in the Greek tradition, the use of olive oil is not allowed at all on the strictest days, when 'xerophagy' is required, while in the Russian church all oils are banned on strict days of fasting. In practice, most Greeks do not extend the ban to vegetable oils other than olive oil, and so sesame oil (and tahini) and other nut or seed oils are allowed.* That said, from a traditional standpoint, frying in any medium is something one should avoid on strict fast days. The overarching directive that one refrain from eating rich foods on strict fast days seems to speak against the consumption of fried foods.
On strict days, when xerophagy is required, olive oil and wine are out, as well as (of course) all animal products (meat, cheese, eggs); also prohibited are fish with backbones. Mollusks and shellfish are allowed... I would guess that insects are okay too but that doesn't come up in discussions too often. Olives themselves as a food are also allowed, just not the oil.
So then, for eating out on days when xerophagy is required, one is faced with the problem of having to avoid olive oil. If the falafil is fried in something other than olive oil, well, that's good, but some would say that fried food is not really appropriate on general grounds, as mentioned above. Bread, olives, a salad with no dressing (at least not with olive oil), boiled grains and vegetabes, and fruit, honey, nuts... that's what it's supposed to be, and I find it rather hard to eat out and stick to that regime... For less strict days, I find Middle Eastern places always a good option; on strict days, one can request that dishes such as hummus are not finished with the usual bit of olive oil. Dolmades filled with rice are a typical fasting dish but again, the issue of olive oil might come up secondarily. So then, for example, pita with olives and hummus works well, as long as no olive oil is used to finish the hummus.
Since for those following Greek Orthodox traditions olive oil is an issue, I think that Asian restaurants are a particularly good option, as long as one sticks to non-fried dishes and focusses on boiled and steamed vegetables, rice and, for protein, one eats only tofu or the appropriate seafood varieties, so long as they're grilled or boiled... Or raw... Sushi could work too, so long as one avoids fish with backbones on days when xerophagy is required.
At last year's symposium in Oxford I presented an historical account of Greek Orthodox and (old fashioned) Roman Catholic rules for fasting along with an analysis of some of the differences between the two traditions; the article will apppear in the forthcomiing volume of proceedings for 2011 (
Celebrations), due out in July.

* Indeed, in practice, many of the old rules for fasting in Greece are no longer observed very carefully by broad sectors of the population, just as among Roman Catholics fasting rules have over time been increasingly ignored and even officially reduced to a piddling few... and even those piddling few are broadly ignored.
