Please make RESERVATIONS with Joydeep Bhattacharyya via email or at 571-269-8432 before the Tuesday before each meeting by 5 PM (17:00). When making your reservation be sure to leave a number where you can be contacted. We now meet in the glassed-in room at the back of the main dining room—The Fife and Drum.  We order individually from the Club menu, which has a nice variety of dinner offerings.  We pay a single bill (I pay it with my Officers Club credit card), so we collect at least $25 from each diner with the agreement, that if one orders more than $20 in food and drink, he adds the amount over $20 to his contribution.  The $5 overcharge goes to the Room Fee, Tax, Gratuity, and the Speaker’s Dinner.  We collect on the Honor System.  We did this for the first time in September, and it worked well.  This room change and use of the menu have greatly reduced the loss that we have incurred in the past for having fewer than 20 people dining, and the change has preserved the viability of using the Officers Club for our meetings. You do not have to pay for the dinner to attend the talk. Reception is from 6:30 to 7:30 PM, dinner from 7:30 to 8:30, and talks are from 8:30 to 9:30. Non-members and guests are welcome.
