If you haven't been to Lumen nightclub in the Warehouse District (839 W. Fulton Market) since it first opened nearly two years ago, you might want to schedule your next visit for Saturday, Jan. 31 when the club reveals its newly enhanced space at 9 p.m. The lounge already known for its high design, eco-friendly materials and multi-media system is getting even more swank with custom-built elevated seating, an extended banquet area, new furniture and added dance areas. Look for a darker color scheme and a new video projection system that will cast ''video wallpaper'' throughout the space, including the ceiling. If you just can't wait to get out on that dance floor, don't worry – Lumen will not be closed during its regular hours of operation as the new enhancements are added.
For reservations, call 312-733-2222. Hours are Tuesday 10 p.m. to 2 a.m.; Friday 9 p.m. to 2 a.m. and Saturday 9 p.m. to 3 a.m.
