Haifa Cafe's South Loop location opened a week ago on the west side of the block of Clark between Van Buren and the Congress Expressway, adjacent to the Royal Loan Bank and Hotel Men Only. I had a good falafel sandwich there yesterday. Plenty of dishes on the menu tempt me; I'm eager to return. Haifa #4 closes at 4:00 p.m. on weekdays and is closed on weekends, though, so I'm still having trouble finding places close to the La Salle St. Station open for a quick bite on weekend evenings. There are places on Printer's Row (the Thai place in the Transportation Bldg., the Gourmand coffeehouse, and Hackney's), but on the immediate flanks of the train station, Boni Vino is the only place that seems to be open after dark on Saturday and Sunday. Any tips, Chowhounds? Thanks.
